TURPENTINE-STILL KETTLE. I

Be it known that I, ULros ZIEBOLZ, a citizen. of the United States, residing at Valdosta, State of Georgia, have invented certain new and useful Improvements in Turpentine- Still Kettles, of which the following is a.

specification.

My invention relates to turpentine still kettles. I

The primary object of my invention is to construct a turpentine still kettle insuch a v manner that the old fashioned manner of riveting various sections of the kettle toa new oint'pro gether is eliminated and tight, durable and vided which is absolutely eificient.

Another object of my invention resides in the provision of a brazed joint in connection with various sections of my kettle which is particularly efficient, durable-and simple in its construction, and is one essentially adapted to use in kettles of this kind wherein the various portions of the kettle are subvaried temperatures,

jected to an enormous amount of wear, and other deteriorating extraneous elements.

A still further object of my invention resides in the provision of a turpentine still kettle which is simple and efficient in construction, very easily manufactured, and extremely practical when placed in use.

With these and other objects in view my invention resides in such details in construction, combination and arrangement of parts as are illustrated in the accompanying drawings, described in the specification and claimed.

'In the accompanying drawings wherein is illustrated the preferred embodiment of my invention, Figure l is a sectional side view of the same showing to advantage the general configuration and location of the various joints. Fig. 2 isa sectional side view of the lap joint, used in my invention before the same has been bent over upon itself.

The preferred embodiment of m invention s shown to advantage in Fig. 1 of the drawings and comprises 'a body portion 1 and bottom 2 and a breast 3. Provided in the central portion of the breast 3 is an opening having the walls thereof bent upwardly to form flanges 4. Within the said openmg 1s dlsposed an intake pipe 5 having the walls of its lower'end flared-outwardly to form flanges 6. The flanges 4 and 6 abut against the surface of the intake pipe and the breast respectively. The eted' y means of a plurality of rivets 7 to form a durable and tight joint. The breast 3 is securedto the body portion 1 of my kettle by means of the joint nated by 8, the particular construction of which will be hereinafter referred to. The bottom' 2 is are shape in cross section and has formed on its edges an annular-uped with the body portionbj a connection generally designated water tight by 10 which Wlll be hereinafter referred to. The outlet or spout 11 is journaled through a cut away portion formed in the lower edge of the body portion, and is provided with a flange 12 and an extension 13. 'The flange'l2 and the extension 13 are formed by means of flaring the inner end of the said outletv 1-1, the upper portion of-said flared portion being bent upwardly and slightly outwardly from the surface of the outlet 11; the extension 13 is bent slightly upwardly from the outlet 11. In order, to provide a water tight connection between the outlet 11 and the body portion 1, I dispose the flange 12 and the extension 13 in abutment with the body portion and bottom respectively. In order to reinforce the connection, I provide an annular flange 15 upon the body portion which embraces and abuts against the outlet 11; an extension is also formed by bending a, portion of the fiangeformedupon the bottom 2 to embrace the remaining portion of the outlet 11. In addition to a water tight connection between the outlet, the body will be hereflange 6 is rivgenerally desigwardly extending flange 9 which is connect- 17 as is shown at inafter referred to, I provide a plurality of rivets in order to hold the entirety in position.

Having thus described the general construction of my kettle I would call particular attentionto the manner in which I secure various sections of my kettle together.

Referring first to the connection generally designated by 8 and clearly illustrated in Figs. 2, 3 and 4, the numeral 1 designates a section of the body portion, and the numeral 3 represents the breast. In order to construct my connection, I provide an annular flange 16 upon the body portion and an annular flange 17 of less width than the flange 16 uponthe, breast. The first operation in constructing my connection is to secure the flanges together in juxtaposition by any suitable means (not shown) and then to bend the flange 16 over and about the flange 18 and clearly illustrated in Fig. 3. The last operation in the formation of my connection is to bend both the flanges 16 and 17 downwardly and abutting the breast as is shown in Fig. 4. When in this position theend of the flange 16 which overlaps the flange 17 at 18 abuts against the breast 3 and in the inclosure formed by the flange 16, the flange 17 forms a hook shaped member which not only prevents displacement of the breast with respect to the body portion but provides a water tight connection which is absolutely dependable. In calking this joint or connection I place a solid base against the interior of the connection and drive the parts forming the same into abutting relationship with each other. This provides a smooth interior and a rigid connection.

As a means for connecting the body portion with the bottom, I provide what is called a brazing joint or connection. In order to accomplish this connection it is necessary to interiorly bevel the flange 9 as shown at 19 of the bottom along the dotted lines 20 as is clearly illustrated in Fig. 5. After accomplishing this operation an annular concave portion 21 is formed in the flange 9 adjacent This concave portion 21 is formed by striking the metal forming the flange 9 outwardly so that the hollowed out portion of the concavity is disposed on the inside of the flange. A concave portion adapted to register with the concave portion of the flange is formed in the body portion. This concavity is designated by adjacent the lower edge of the body portion, and is adapted to fit or be retained within the concavity 21. In order to retain the body portion in connection with the bottom, I provide a plurality of rivets 23 through the material forming the concave portions 6% and when such rivets are driven and fin- .body portion is the beveled portion 19.

22 and is formed ished as is shown in Fig. 7 the body portion and bottom are'held securely together. It is necessary, to perform the functions of my invention, to provide absolutely tight connections. In order to accomplish this purpose I pour, in the space between the'beveled portion 19 and the body portion, a brazing metal which may be of any desired kind provided it'has a lower melting point than the metal used in the construction of my kettle. I prefer to use brass spelter for this purpose. This brazing as designated by 24 provides an absolutely tight connection, reinforcing materially the constructlon of my connection. Fig. 7 illustrates the last operation in forming my joint between the bottom and body portion, namely, that of calking. To perform this operation the interiorly supported by some stationary base and the base flange driven down thereupon thus forming an off-set portion in the flange wherein the body portion is retained. This step in the construction of my kettle may be, and preferably is, formed simultaneously with the finishing of the rivets.

I find it desirable to form my connection between the body portion and the bottom in the following manner: After beveling in any suitable manner the flange upon the bottom, and forming the concavities in the body portion and flange, I fit the body portion within the flange and bore the rivet holes therethrough by means of any suitable tool. The rivets are then driven within the holes and clenched to securely hold the members rigidly in connection with each other. I then dispose my brazing material in the space provided therefor; I find it desirable to melt the brazing material by means of a powerful torch, that is by melting the brazing material sufiiciently by heating the material forming the flange and body portion. By so doing a gradual melting of the brazing material is eflected thus allowing it to fill up all open places in the connection making a very strong and tight union. The brazing is then scoured or finished and the rivets and calking perfected.

In connection with the placing of the spout or outlet I find it desirable to make this the last operation of the construction in my kettle. After every other element of my kettle is placed in the proper position and secured, the outlet is placed within the opening provided therefor and has its flange and extension brazed to the bottom and body portion respectively. 'The rivets are then finished OE and the kettle is complete and ready for use.

In the accompanying drawings and in the above description I have shown only the preferred form of my invention. Conditions coincident with its reduction topractice may vary, necessitating slight changes ters Patent is:

In a turpentine still kettle, the combination with a body portion and a bottom, of an outlet pipe carried thereby, said body portion being provided with an opening for the reception of said outlet pipe, said outlet pipe having a flange formed on one edge thereof, said flange extending substantially at right angles to the surface of said outlet pipe, and gradually increasing to an obtuse angle opposite said right angle portion, flanges surrounding said opening in said body portion and a flange formed on said bottom, rivets for securing said flanges on said outlet pipe to said bottom and said body portion, said flange on said outlet pipe having its edge adjacent said bottom and said body portion beveled, and brazing material adapted to be disposed between said flange on said outlet pipe and said body portion and said bottom in the opening provided by said beveled portion to provide a tight connection.

/ In testimony whereof I affix my signature in presence of two witnesses.
